Controllers - Programmable (PLC, PAC)Programmable logic controllers (PLCs) and programmable automation controllers (PACs) are electronic devices that are used to control industrial machines and processes. These controllers use a programmable memory to store instructions and data, and use these instructions to control the operation of the machine or process. PLCs and PACs are commonly used in a wide range of industrial applications, such as manufacturing, process control, and material handling. These controllers are typically small and compact, and can be easily integrated into a wide range of industrial systems. PLCs and PACs are highly versatile and can be programmed to perform a wide range of control functions, making them a popular choice for use in a wide range of industrial applications.
